Embodiments described herein generally relate to devices, systems and methods for measuring a volume or number of doses remaining in a drug delivery device that is used for delivering a dose to a patient. In some embodiments, a dose measurement system for measuring the liquid volume in a container includes a light guide disposed and configured to reflect electromagnetic radiation toward the container. The dose measurement system also includes a light guide disposed and configured to emit electromagnetic radiation into the light guide. A plurality of sensors are located in the apparatus that are optically coupleable to the light guide and are disposed and configured to detect the electromagnetic radiation emitted by at least a portion of the light guide. The apparatus also includes a processing unit configured to receive data representing the portion of the detected electromagnetic radiation from each of the plurality of sensors. The processing unit is further operable to convert the received data into a signature representative of the electromagnetic radiation detected by the plurality of sensors.

A delivery device for delivering a medical fluid to a patient has a housing configured for receiving a container at least partially filled with the medical fluid. The delivery device further has a drive mechanism associated with the housing configured for delivering the medical fluid from the container to the patient in a dosing procedure. The delivery device further has a module configured for detecting at least one of a property of the dosing procedure and a property of the medical fluid. The module has at least one dose detection sensor configured for detecting an initiation, progression, and completion of the dosing procedure based on a position of a stopper within the container. The module further has at least one temperature sensor configured for measuring a temperature of the medical fluid within the container based on a temperature of the container.

A wireless data communication accessory is disclosed, which is configured for attachment to a drug delivery device and comprises an interface for data exchange between the accessory and the drug delivery device, wireless communication means configured to communicate with an external device paired with the wireless communication means via wireless communication, and a controller coupled to the interface and the wireless communication means and being configured to control operation of the interface and the wireless communication means such that data received from the drug delivery device via the interface are processed for transmission to the external device via the wireless communication.

A device is presented having an electronic circuit, where the device can be a medicament delivery device or a medicament delivery device add-on component that includes an electronic circuit having a temperature sensor configured to measure a temperature, where the electronic circuit is configured to passively remain in a first mode when the temperature is on a first side of a set temperature and to transition to a second mode when the temperature transitions to a second side of the set temperature. In some embodiments, the electronic circuit can have one or more of a feedback portion configured to switch from a first state to a second state in response to the electronic circuit transitioning from the first mode to the second mode, a lock, and a recordal portion to record when the electronic circuit transitions from the first mode to the second mode.

A device for dispensing a controlled amount of a fluid from a syringe, the syringe having a plunger extending along a linear axis through a syringe flange and into a syringe barrel. The device includes a housing to accommodate at least a portion of the syringe, and a drive wheel attached to the housing to contact a side of the plunger, the housing to press the drive wheel into the side of the plunger between the syringe flange and an end of the plunger.

Modules for housing electronic and electromechanical medical equipment including a system to measure and record administration of one or more IV medications or fluids for IV administration.

The present disclosure relates to an activation system for a supplemental device that is attached to an existing design of a medicament delivery device, where the removal of a protective cap or other covering from the medicament delivery device pulls a blocking element from between electrical contacts to close a circuit between a battery module and a power source, thus activating the battery module. The supplemental device can further have a transmitter for communicating information about the use of the medicament delivery device to an external device, such as a smart device. Memory storage elements can also be included having unique identification data. The present disclosure also relates to a medicament delivery device having attached the supplemental device.

An injection device (1) comprising a housing (10), a syringe (2) having an injection needle (4) covered by a needle shield (5), and a cap assembly (3) comprising a cap body (15) covering a distal end of the syringe, and a shield remover (9) adapted to engage the needle shield (5), the shield remover (9) being axially fixed relative to the cap body (15). The cap assembly (3) further comprises an elevation member (12) being movable rotationally and axially relative to the cap body (15), wherein the elevation member (12) comprises a first rotation preventing geometry (18, 28, 31) configured to prevent the elevation member (12) from rotating relative to the housing (10), and a cam interface (20) with engaging cam surfaces respectively disposed on the elevation member (12) and the cap body (15), the cam surfaces being configured to engage slidingly upon rotation of the cap body (15) relative to the housing (10) so as to cause a proximal facing surface (17) of the elevation member (12) to be axially forced against a distally facing surface (16) fixedly disposed relative to the housing (10) while moving the cap body (15), the shield remover (9) and the needle shield (5) distally relative to the housing (10).

An integrated closed-loop artificial pancreas includes: a detection module; a program module which is imported into the total daily dose algorithm and the current insulin infusion algorithm; and an infusion module which is connected to the program module. The infusion module includes an infusion tube which is used as the insulin infusion channel, the detecting electrodes are provided on/in the wall of the infusion tube, and the infusion module can infuse insulin required according to the data of the current insulin infusion dose. It takes only one insertion to perform both glucose detection and insulin infusion.
